Hook
Search "AI receptionist" and you'll find forty vendors, all claiming to be affordable, almost none publishing a straight number next to a straight answer on what you get for it. The pricing ranges from $0.05 a minute to $2,100 a month — a 100× spread for products that all promise the same sentence: "never miss another call." Here's what each pricing model actually means in a real month, verified against the vendors' own pages.
The Three Price Bands (All Verified 2026-10-14)
| Model | Who sells it | What it costs (checked 2026-10-14) | What the headline doesn't say |
|---|---|---|---|
| Usage-based voice AI (build-it-yourself platforms) |
Vapi; Twilio (components) | Vapi: $0.05/min hosting + AI-provider passthrough (~$0.03–0.08/min more) — realistically ~$0.08–$0.13/min all-in; $5 free credits (checked 2026-10-14). Twilio: numbers from $1.15/mo + per-minute/per-message metering (checked 2026-10-14). | You're buying parts, not a receptionist. Someone has to build, prompt, test, and maintain the agent — either you or a contractor. The per-minute price is real; the "just plug it in" story isn't. |
| SMB AI receptionist products (the ads you keep seeing) |
Upfirst, Dialzara, My AI Front Desk, Goodcall | Upfirst: $24.95/mo (30 calls) → $299/mo (600 calls). Dialzara: $29/$99/$199/$349/mo + per-minute overage. My AI Front Desk: $99/mo ($79/mo annual), ~200 min. Goodcall: $79/$129/$299/mo. (All checked 2026-10-14.) | Plans are capped by calls or minutes — the "from $29" price covers a low-volume month. Check the overage rate (Dialzara bills $0.35–$0.48/min over your cap, checked 2026-10-14). This is where most appointment businesses land. |
| Human-backed reception (AI-assisted humans) |
Smith.ai | $300/mo for 30 calls; $810/mo for 90; $2,100/mo for 300; ~$8.50–11.50/call overage (checked 2026-10-14). | Not pure AI — real people answer, which is why it costs 10× the AI products. The right comparison isn't Upfirst, it's a part-time hire. If calls must be handled perfectly (legal intake, high-ticket sales), this is the honest price of that bar. |
| The free baseline (what you're comparing against) |
Google Voice + missed-call text-back | Google Voice Basic $0 personal / Starter $10/user/mo; Quo (OpenPhone) $15/user/mo annually with auto-replies built in; Sona AI add-on $0–199/mo. (All checked 2026-10-14.) | An auto-text-back isn't a receptionist — it can't answer questions — but it catches the caller's intent in seconds for a tenth of the price. For most small books, this is the correct first step and for many it's the only step needed. |
Which Band Is Yours
- Under ~10 missed calls a week, appointments under ~$200: You do not need an AI receptionist. A $15–25/mo text-back (checked 2026-10-14) covers the leak for a tenth of the price. Run your numbers on the missed-call cost table first.
- 10–30+ missed calls a week, or calls that need questions answered (services, pricing, availability): The middle band — $25–$100/mo products (checked 2026-10-14) — is where the math works. Watch the call caps: a "cheap" plan with a $0.45/min overage rate stops being cheap fast if the AI is good enough that people actually talk to it.
- Every call is high-value or high-risk (intake quality matters more than speed): Look at the human-backed band, and compare it honestly against a part-time human — $300/mo for 30 calls is ~$10/call (checked 2026-10-14), which is only cheap if a part-time receptionist can't do it better.
- You're technical or already paying a developer: The usage-based platforms are genuinely the lowest cost per call — but price in the build and maintenance hours, or you're comparing a parts kit against an appliance.
The Costs That Aren't on the Pricing Page
Every vendor named above has a full Wall Check — price, permission, gate, meter and exit, each one screenshotted against the vendor's own pages. Open the vendor's wall page before you open its checkout.
- Per-minute overage. Ask for the overage rate before you sign, not after the first busy month.
- A2P registration. Any vendor texting your US callers runs through carrier registration (TCR) — human-reviewed, days of lead time on some platforms (Quo documents this; Twilio requires it). "Live in five minutes" is marketing for the part that isn't gated.
- Your number. Check exit terms: does your business number port out cleanly, and does your call/message history come with it? Numbers usually port; transcripts usually don't.
- The awkward-caller tax. Every AI receptionist handles the easy 80% of calls. The question that matters is what it does with the angry, confused, or ready-to-pay weirdo on call 81 — read the vendor's escalation path before you read its testimonials.
The Bottom Line
For a solo operator or small appointment book: start with the free/cheap baseline (missed-call text-back, $15–25/mo — checked 2026-10-14) and measure what it recovers for a month. If calls still leak — because callers have questions a text can't answer — the $25–$100 AI-receptionist band (checked 2026-10-14) is the next step, chosen by call volume, not by ad. Save Smith.ai's $300+ human tier (checked 2026-10-14) for when call quality is provably worth more than call coverage. Every price on this page was checked against the vendor's own page on 2026-10-14; we take no money from any of them, so we don't care which band you're in — only that you didn't get upsold into it.
Head-to-head: the four pricing models, verified again 2026-11-09
The four platforms behind most AI-receptionist quotes were re-checked against their own pricing pages on 2026-11-09 — Vapi ($0.05/min + pass-through), Dialzara ($29–$349/mo + $1,500/mo Done-For-You tier), Goodcall ($79–$299/mo per unique customer), and Podium (quote-gated, no published number) — all checked 2026-11-09. The head-to-head teardown — including the overage rates and the exit terms — is on the AI voice receptionist pricing comparison.
